Net installation requires a variety of hardware

StealthNet bird netting is one of the most versatile solutions for bird control, providing a discreet yet effective barrier against all types of nuisance birds without inflicting harm on the birds themselves. StealthNet products offer you a permanent way to stop bird droppings from damaging your valuable property. Available in several colors, you can choose netting that blends into the background, providing a robust but unobtrusive defense against pest birds.

How StealthNet Bird Netting Works
Constructed with steel and extra-strong strands of polyethylene twine, the StealthNet bird exclusion system creates an impenetrable barrier that denies birds the access to any architectural structure on your property. The StealthNet system includes tensioned cables that are attached directly to the application site. The netting is then attached to the cable with rings, enabling a secure fit while allowing you to access the enclosed area for routine maintenance.

Versatile Bird Control Solutions
The StealthNet system lets you stop bird droppings virtually anywhere on your property, including ledges, eaves, utility enclosures, vineyards and ponds. It's one of the most cost-effective solutions for large open areas such as open-air ceilings and loading bays. Available in multiple mesh sizes, StealthNet netting can create a durable and long-lasting barrier against birds of any size. Both pre-cut and custom netting sizes are available.

Bird Barrier is pleased to offer all the hardware needed for StealthNet installations, including corner bolts, turnbuckles, brackets, clip and clip attaching tools. Should you need help with installation, our knowledgeable field representatives are available for technical support. StealthNet's manufacturer can recommend certified installers as well. At Bird Barrier, our mission is to provide you with everything that you need to prevent pest bird damage effectively and humanely.

StealthNet Bird Netting is Almost Invisible
StealthNet is available in stock colors of black, stone (beige) and white. The netting is composed of very thin, ultra-strong strands of polyethylene twine.

How to Install StealthNet Bird Netting
StealthNet can be installed using a variety of fastening devices created specifically for your building's needs. Whether it's masonry, steel or wood, we offer a discrete suspension system for a maintenance-free, permanent installation.

Installation Instructions



StealthNet installation can be very complicated if you don't think it through properly in the beginning. However, with good planning, it is a very easy proposition.

There are seven elements in every netting job. If you pick the correct piece of hardware for each of the seven elements, you will be able to install a professional, effective and long-lasting netting application every time. The basic configuration of every net job is a strong, tensioned cable which borders an opening to which netting is later attached. The cable is attached to the building using a variety of hardware attachments, and the netting is attached to the cable using net rings.

Following is a rundown of the seven basic elements in a net job:

1) Corner Attachments

Corner attachments are the most important part of a netting installation. They are used where cables turn cor- ners or where cables end. They with- stand a great deal of pressure.

There are two important consider- ations regarding corner attachments—where you install them and which ones you choose.

The location of corner attachments is usually quite sim-ple to determine. It is where natural corners fall in the shape of the net or where cables end at a wall. When netting off a square opening on the side of a building, the corner attachments are placed in each corner (four). When a three dimensional job is installed, corner attachments may be placed on opposite walls with a cable running between them. This cable forces the net to take a corner.

The choice of which attachment to use is determined by the substrate material surrounding your job. If you are working with concrete, you need to install netbolts that expand when you tighten them (see corner attachment page in the catalog). Likewise, if you are working with wood, you need to use corner attachments which fasten into wood. These anchors must be strong because great tension will be applied by the system, and the corners will take most of the strain.

2) Intermediate Attachments

Like the corner attachments, the intermediates also hold the cable to the structure. In this case, however, the job of these fasteners is to hold the cable tight against the wall along the side of the net job, so the cable will not bow away and allow birds to enter the bird-free zone. If the cable were attached in just the corners, the tension of the netting would pull the cable away from the walls. The inter- mediate attachments, when placed every few feet along the run of the cable, prevent this from happening. For pigeons and larger birds it is acceptable to install them every three to four feet. For smaller birds, like sparrows and swallows, the attachments must be much closer together (no more than two feet), so small birds cannot get behind the cable gaps. All of Bird Barrier's intermediate attachments are designed to be strong yet discreet.

Different intermediate attachments are available for different substrate materials. Attachments are available for stone, steel, wood, sheet metal and stucco. Hardware is available in galvanized or stainless steel versions. Please refer to the Intermediate Attachments section (pages 12-13) of Bird Barrier's product catalog.

3) Perimeter Cable

As previously stated, the cable frames the entire net pro- ject and forces the net to take corners on three dimension- al jobs. Bird Barrier's cable is available in galvanized and stainless steel. The cable is designed to be exceptionally strong, yet very hard to see. The cable may be used under large panels of netting on outdoor, horizontal applications (like over a courtyard), and is especially critical if snow or ice could build up on the netting. The cable is looped at one end through the corner attachment, runs through every intermediate attachment, and is looped at the other end through the turnbuckle (see below).

4) Intermediate Attachments

The cable is tensioned between corner attach- ments and through interme- diate attachments with turn buckles. These small screw-tensioning devices can exert thousands of pounds of ten- sion on the cable, so it must be strong and the corners must be anchored securely.

There are three different turnbuckle sizes all of which are available in galvanized and stainless steel. Small turn- buckles are for cable runs under 25 feet. Medium turnbuck- les are used for cable runs between 25 and 75 feet, and large turnbuckles are for cable runs above 75 feet. It is important that the turnbuckle is opened all the way and that the cable is pulled as tight as possible before the loop is crimped to take up as much slack and stretch in the cable as possible. For installations under 10 feet in length, the tensioned cable should not be allowed to run throughmore than one corner attachment. For installations over 10 feet, turnbuckles must be used for every straight run.

5) Ferrules and Ratchet Crimper

Ferrules are used to secure loops in the cable at each end (at corner attachments). One loop is fastened to a corner attachment; the other loop to an opened turnbuckle. The ferrules are slid onto the cable before the loop is formed and then crushed around the cable with Bird Barrier's powerful ratchet crimper. When using the ratchet crimper place the ferrule into the middle or end slot with the narrow part facing up and then crimp down once on each end of the ferrule crushing both ends completely (you must crimp each ferrule twice for a strong hold). Always use 2 ferrules per loop for added strength and reliability of the perimeter cable system.This creates a strong, yet discreet, loop.

6) Net Ring Loops

The netting is fastened to the cable using a special Net Ring tool. This tool loops a small piece of metal around the netting and the cable. It is easy to use, carries a cartridge of 50 rings, and is the fastest and strongest way of attaching the net to the cable. Use one loop per square of netting. To estimate the amount of Net Rings for the job, multiply the number of net rings per foot by the total feet of cable being used. For example:

2" Net = 6 Net Rings per foot. 3/4" Net = 16 Net Rings per foot, or 8 if you skip every other square.

Net rings come packaged 2,500 to a box.

7) Selection and Attachment of the Netting

Now that the cable frame is in place, it is time to install the net that best matches your building's color and bird control objectives. The color net you chose should reflect the dom- inant color of the building. StealthNet is available in 4 dif- ferent colors: black, stone (beige) and whitel. The most commonly used color, and often the most commonly used often the least visible, is black StealthNet. Stone netting is against beige, brown, and other sandstone buildings. White StealthNet works best against white buildings that are not exposed to direct sun reflection or bright lights. This is due to the light reflection properties of white colors. Black should be used if bright light, like sunlight, will shine directly on it.

StealthNet is designed in three standard mesh sizes (size of each square) depending upon the species to be excluded. They are as follows:

3/4" - Sparrows, swallows, small birds and all large bird species
1-1/8" - Starlings, black birds and all larger bird species
2" - Pigeons and all large bird species
4" - Gulls and other large sea-birds

Custom-designed mesh sizes can be created for unique species (special order product; 8-10 weeks). StealthNet is available in a variety of standard sizes and can often be cus- tom fitted to meet your projects needs. See Bird Barrier's product catalog or call Bird Barrier for sizes and availability.

8) Access to the Netted Area


Once the net is in place, access to the area may be gained with the use of either zippers or net clips. To install zippers or net clips simply set them on top of the installed net where access is desired. Attach the zipper by net ringing through the cloth of the zip- per while grabbing the net strand as well. Net ring up both sides of the zipper to hold it firmly in place. Finish by unzipping and cutting out the middle net strands. When using net clips, slip the clips onto each side of the mesh opening and cut out the net strands between that the clips will replace.

Un-Bundling Your Net
When you receive the net, you will notice that identification tags mark each corner of the net and in the case of rectan- gular shaped nets, a special tag is used to identify the long side of the net. To unfold the net, locate the strings that are used to mark the corners and pull the net out flat. The net will appear to be diamond shaped before being fully stretched out. Call Bird Barrier if you have any questions about our products.

When attaching StealthNet, begin working from one corner and attach the net with net rings in a straight, even row in one direction. After you have a few feet attached, go back to the same corner and attach a foot or two in the opposite direction so that the net is firmly attached in that corner. Finish net ringing one of the rows entirely, preferably the length (longest) side if it is a rectangular net. Once you have finished the row, go back to the beginning corner and go down in the perpendicular direction. Now that you have the top and one side finished, you can either do the bottom or the other end. When the netting is completely secured to the cable, check your cable. If the cable is bowing away from the building with a gap larger than the mesh size of the netting, tighten the turnbuckle (this will tighten the cable and close the gap)

ALL NETTING ATTACHMENT MUST BE DONE IN ONE DIRECTION ONLY! NEVER attempt to work from opposite ends and meet in the middle!

Netting is a complicated installation and Bird Barrier recommends new installers attend our two day training course and review our installation videos to help lessen the chance of costly errors.

Additional Installation Assistance
While actual net installations are often very easy, some jobs can be very complicated, time-consuming affairs. The best installers have many successful jobs under their belts and learned most of their lessons on the job. Obviously a few pages of text and pictures in a manual cannot hope to make you a professional net installer, but Bird Barrier's How-To Netting video just might do a better job.

CSI Division 10296 Bird Barrier StealthNet and Intallation Hardware Systems

MR-Manufacturer

Bird Barrier America, Inc. manufactures StealthNet from ultra- violet stabilized strands of polyethylene plastic. Installation hardware is available in both galvanized and stainless steel options.

PR-Product Presentation

Total Bird Exclusion
Bird Barrier's StealthNet offers the latest technology in total bird exclusion of sparrows, starlings, swallows, pigeons, gulls, crows and any other pest bird. StealthNet is fast becoming the most widely used netting for bird exclusion across America.

Strong, Versatile Netting
The net is made from high density, ultra-violet stabilized polyethylene twine, a material that will last ten years or more if installed correctly. Because StealthNet is knotted from a strong cabled twine, it is more than five times stronger than inferior plastic molded nets; it will not rip apart under normal stress, or sag over time.

Invisible
StealthNet's twine, while very strong, is actually very thin. And because it is available in black, white, stone (beige) and the net can always be chosen in a color that will blend in with the background. The final result is always a secure and permanent solution that is very hard to see.

Multiple Mesh Sizes
Because pest birds vary in size, StealthNet is available in different mesh sizes for different birds. For example, 3/4" mesh for sparrows and swallows, 1-1/8" mesh for starlings, 2" mesh for pigeons, and 4" mesh for gulls and crows. Obviously, smaller birds can penetrate larger mesh nets, so care must be taken to identify the pest birds correctly.

No Size Limit
StealthNet is readily available in a whole host of pre-cut sizes, from 25' x 25' up to 50' x 100'. And, for no extra per-foot cost, it is available in custom sizes up to 500' x 500'. That means large net jobs can be installed without seams which take extra time and weaken the overall net job.

Access Behind Net
StealthNet zippers or net clips can be installed in the netting in any application to allow for access to enclosed areas, maintenance, changing of light-bulbs, etc.

Many Uses
StealthNet has literally thousands of applications including: courtyards, warehouse ceilings, bridge undersides, air conditioning enclosures, signs and billboards, church steeples, ledges, balconies, alleys, loading docks, hangars, patios, eaves, roofs, ponds, vineyards and faces of entire buildings.

Installation Hardware
StealthNet's comprehensive hardware has options for any mounting surface including stone, concrete, steel, wood, stucco and brick. A strong cable system is actually bolted or fastened securely to the building before the netting is installed. This insures a strong, solid, non-moving system that will not weaken over time. And because all fixtures are mechanical (no adhesives, Velcro etc.), you can be assured of an installation that will stand the test of time. Specialized tools for the netting and hardware are available from Bird Barrier.

Call 800-503-5444, or fax drawings and other pertinent information to 310-527-8005. Free literature, catalogs, job evaluation worksheets and installation information is available.

Due to the complexity of the average StealthNet installation, it is highly recommended that the manufacturer is contacted directly, and that knowledgeable, certified installers be used to insure the best, long-lasting results.

StealthNet's Thermal Properties
Softening Point: In the region of 250 degrees Fahrenheit. Melting Point: In excess of 270 degrees. Burns with difficulty, flame will not spread. May be heated for short periods up to 600 degrees.

Low Temperature: Retains its flexibility at very low temperatures and does not become rigid under freezing conditions.

StealthNet's Chemical Properties
Polyethylene, being a paraffin hydrocarbon, is inherently chemically inert and is highly resistant to a wide range of chemicals at ordinary temperatures. It does not rot and does not absorb water. Polyethylene fibers have a high resistance to acids and alkalids of all concentrations. They are insoluble in most common organic solvents at room temperature.

StealthNet's Electrical Properties
Polyethylene is an outstanding electrical insulator, especially to high frequency currents.

Effects of Insects and Micro-organisms
The fibers are not digested by insects and are completely resistant to bacteria, mildew and other micro-organisms. This makes StealthNet virtually rot-proof.
